SPRING-WHEEL.

Specification of Letters Patent.

Application filed April 4, 1916. Serial No. 88,897.

To all whom it may concern:

Be it known that I, GEORGE W. WAT'rs, a citizen of the United States,and a resident of Hot Springs, in the county of Garland and State ofArkansas, have invented a new and useful Improvement in Spring- VVheels,of which the following is a specifieation.

My invention is an improvement in spring wheels, and has for its objectto provide a wheel especially adapted for use with trucks and like heavymotor vehicles but also adapted for use in any character of motorvehicle, wherein an auxiliary rim is provided arranged concentric to thewheel, and connected to the rim of the wheel by spring mechanism soarranged that shock or jar on the auxiliary rim will not be transmittedto the axle, but will be absorbed between the rim and the wheel.

In the drawings Figure 1 is a side view of the improved wheel with partsin section,

Fig. 2 is an enlarged section on the line 29. of Fig. 1, and

Fig. 3 is a perspective view of one of the springs.

In the present embodiment of the invention, the felly 1 of the wheel isprovided with a quick demountable rim 2 of ordinary construction, and anauxiliary rim 3 is arranged concentric with the wheel, the said rimbeing of such size that there will be an annular space between the wheeland the auxiliary rim.

The auxiliary rim is channeled on its periphery as indicated at 4 and acushion tire 5 i mounted in the channel, the said tire being in thepresent instance of rubber. The auxiliary rim is connected to thedemountable portion of the wheel rim by means of a series of springs,one of which is shown detached in Fig. 3.

Each of the springs is of plate material bent to form a body 6 and arms7 and each arm is provided with a lateral outwardly extending lug 8 atits free end, the lugs being perforated as shown. The body of eachspring fits against the outer face of the demountable portion of thequick demountable rim, and the body of each spring is connected to thesaid portion by means of a bolt 9, which is passed through thedemountable portion of the rim and through the body of the spring and isengaged by a nut 10 on the outer face of the body.

The lugs 8 of the arms 7 of each spring are lapped upon the innersurface of the rim at each side of the connection of the body, and eachlug is connected to the auxiliary rim by a plurality of bolts and nuts11. The heads of the bolts 11 as shown in Fig. 1, are countersunk in thebottom of the channel of the auxiliary rim so that the said heads areflush with the said bottom of the channel.

The inner or concave face of the demountable portion of the quickdemountable rim has an annular groove 12, and the heads of the bolts 9are received in these grooves, being countersunk slightly as shown inFig. 2, to cause the heads to be flush with the highest portion of thedemountable portion of the rim.

Each arm 7 of each spring is bent back upon itself in zigzag or sinuousform as shown to provide for additional resiliency and in the presentinstance six of the springs 6--7-8 are provided, each havin its bodyconnected with the demountable mm and its arms with the auxiliary rim.

It will be evident that when shock or jar is imparted to the auxiliaryrim at the lowest portion for instance, that spring 6-7 which is belowwill be compressed, the laterally bent portions moving toward each otherand the body of the spring moving toward the auxiliary rim. That springwhich is directly above will be expanded, the body moving away from theauxiliary rim. Those springs which are at the sides will be bothcompressed and expanded, the lower with quick demountable rims, since itis obspring comprising a body connected with the 10 vious that thesprings might be attached to wheel rim and arms diverging from the bodythe usual rims. in opposite directions and connected with.
